Malic acid, also known as 2-hydroxy-succinic acid, exists as two stereoisomers due to the presence of an asymmetric carbon atom in the molecule: D-malic acid and L-malic acid. These two isomers, as well as their mixture DL-malic acid, occur in nature in three forms. Malic acid is a white crystalline or crystalline powder with strong hygroscopic properties, soluble in water and ethanol, and has a special pleasant sour taste. It is widely used in the food and pharmaceutical industries.
